I uploaded a small pic of a neon panel lamp assembly to the photos
section to see if anyone knows who manufactures these? They are the
same press in neon lamp lens that Heathkit, B&K, and several others
used for indicator lamps on their equipment. They press in a 5/16"
round hole, and a Tinnerman nut is pressed over the lens from the
rear to hold it. The outer lens you see is about 3/8" OD, and tapers
outward about 1/4" long. The total length is about 7/8" to 1". The NE-
2 type neon lamp is then slid in the rear opening of the lens and
it's leads soldered to the circuit. They are made of a translucent
plastic either clear, red, amber, or green if I recall. I'd like to
buy several hundred of these lens if I can find the manufacturer.

Mouser has a similar smaller version, but they're not translucent,
and are really made to use an LED with. I have some of these too, but
don't like them. I'm needing the larger ones like Heathkit used in
Amber, red, or clear color. These wre used as the power indicator
lamp on a Heathkit IM-5228 and IM-18 bracket mount VTVM.

Francis,

Yes, I've looked at theirs and Chicago Miniatures lamps. They have
some nice stuff. The reason I want these though is two fold. The lens
is really cheap. Buying bulk, the lens itself is about 20 cents each
not counting the Tinnerman nuts. The second and main reason is you
can use either a neon lamp, grain of wheat lamp, or T-1 3/4 LED with
the same lens. Really, any lamp that will fit in a 1/4" diameter
hole. In other words, no matter what the occasion, I can have the
lamp I need for the situation by simply changing out the lamp. I
think this is why Heathkit and others used this type lamp so much.

I used them for several years in some products I made but bought them
through a distributor. I never did know who made them, and now I
can't find a distributor with them. Linrose Electronics makes
something similar, but the lamp is permanantly mounted inside with
epoxy I imagine. There you couldn't re-lamp the lens, and have to buy
the whole assembly over it. Plus, keep one type for each voltage you
want to use. I'm hoping someone might know who made these originally,
or a distributor who carries them.

Thanks,

Will

leds from 5 to 28 VDC (with built in resistor for each voltage) or a

equipment.
